[Zope] Problems with sendmail and attachments

[Klimovich Alexander]

 Hi everybody!

 I have a problem with sending attachments using sendmail tag.
 This is my file:

 <dtml-sendmail mailhost=3D"TOPS_mailhost">
 To:<dtml-var mail_addresses>
 From:klima
 Subject:<dtml-var mail_subject>

 <dtml-mime type=3Dtext/plain encode=3D7bit>
 Attached is the document you requested.

 <dtml-boundary name=3Dreport.htm type=3Dtext/html =
disposition=3Dattachment encode=3D7bit>
 <dtml-var "_[test]">
 </dtml-mime>
 <dtml-var mail_text>
 </dtml-sendmail>

 'test' is a simple html file. I'm getting an error after processing the =
upper file.
 Error is:
 Error Type: TypeError
 Error Value: expected string or Unicode object, ImplicitAcquirerWrapper =
found

 What's wrong ? Any ideas ?


 Thanks,
 Alexander
